by date code the only equivalent Intel ODP parts being made were
40MHz ODP486SX-20 A2 SZ675 9217 - 9240
50MHz ODP486SX-25 A2 SZ676 9217 - 9239

the alternative FRU for 92F0147 is 92F0079
alternative manufacturer part number to 49G2856 is 32G3374
so it is a ODP486DX-25 / ODP486SX-25 (technically the same but different naming)
but only SX version was being made at this time
so will be a 50MHz ODP486SX-25

ODP486DX-25 was never an official part number & never used
even if it was used, there is no physical difference between a DX & SX over-drive
